In their October 2012 issue, Auto Enthusiast magazine featured a transmission upgrade for a '68 Camaro. The new tranny, a modified T56 Magnum-- called a "Tranzilla"-- was converted by Rockland Standard Gear. As AE reported:
"What they do is take the Magnum from Tremec, upgrade to carbon rings on gears one through four, and slap on a Viper tail shaft."
This conversion allows the car to run up to 1,000 lbs-ft. and 1,200 horsepower.
In the process of switching out the transmissions, the techs at Auto Enthusiast noted how pleased they were with the Central Hydraulics 450 Lb. Capacity Low Lift Transmission Jack:
"We have to wrench on our stuff just like everyone else, on the ground. We found this helpful scissor transmission jack at Harbor Freight for $65. Trust us, it was the best $65 we ever spent. It made this job almost too easy." (from slide #4 on the article)
It should be noted that the $65 price came with the use of a Harbor Freight 20% coupon-- so make sure to clip one of those before you shop!
The 450 lb. transmission jack is perfect for removing trannies on small-to-mid vehicles. Riding on smooth, easily-maneuverable 3" swivel casters, this tough jack was forged for rough, long-term use in the shop or garage. The saddle tilts for easy positioning during repair, making it the right tool for any professional auto garage or hobbyist.
